Abstract (en)
Provided are: a sliding plate, the thickness and performance of which can be easily adjusted; and a floor plate for a turnout, using the sliding plate. A sliding plate (3) is provided with a backing material (31) comprising a steel plate or the like, a punching metal (32) disposed on the backing material (31), and a sintered meal powder layer (33) formed on the upper surface (310) of the backing material (31) so as to cover the punching metal (32). The sintered metal powder layer (33) is formed by subjecting an alloy powder for sintering to sintering and rolling, and is impregnated with a lubricating resin through heat melting. The sintered metal powder layer (33) formed on a metal area (321) of the punching metal (32) has undergone high-pressure compression and therefore exhibits a high sintered density and excellent resistance to impact, load and wear. Meanwhile, the sintered metal powder layer (33) formed in empty spaces (322) of the punching metal (32) has undergone low-pressure compression and therefore exhibits a low sintered density and a high impregnation rate of the lubricating resin, thus attaining excellent lubrication.
